APPARATUS USED IN THE MANUFACTURE OF ARTIFICIAL SILK.

Specification of Letters Patent. Patented Sept. 18 1917.

Application filed. April 18, 1916. Serial No. 91,986.

To all whom it may concem:

Be it known that I, JAMns CLAYTON, a subject of the King of Great Britain, residing at 12 Middleborough road, Coventry, England, have invented new and useful Improvements in Apparatus Used in the Manufacture of Artificial Silk, of which the following is a specification.

In apparatus employed in the manufacture of artificial silk by squirting a solution of cellulose into a setting bath through a nozzle and leading, by guides, several threads thus formed upward and then downward through a tubular guide into a spinning box in which the threads are twisted. together and made into the form of a coil, it has been customary to move the tubular guides up and down by mechanism operated from above and occupying some considerable space at the sides of the upper part of the apparatus. This method of working has the objection that the reciprocations of the tubular guides cause irregularities in twisting and it is the principal object of this invention to overcome this objection and incidentally to obtain other advantages as hereinafter explained.

According to this invention the spinning boxes are made to reciprocate in an upward and downward direction .in place of reciprocating the said tubular guides. By this means the objectionable effect of the movable tubular guides upon the twisting of the threads is overcome and a much more evenly twisted product is ,obtained, while the coiling is efliciently performed by reciprocation of the spinning boxes.

The reciprocation of the spinning boxes can be eflected by any-suitable means; it is preferably efl'ected from below.

A convenient method is the following, resuming that the apparatus consist of a onble series of spinning devices arranged in rows one on either side of the longitudinal center line of the apparatus.

I will, in further describing the invention, refer to the accompanying drawing which represents, (in vertical section in Figure 1 and in side view of a portion in Fig. 2) sufiicient of a machine to illustrate the application of this invention thereto, but it is to be understood that this invention is not limited to the details illustrated in the drawing and described with reference thereto.

The spinning boxes 1 are shown as being each mounted on the vertical spindle 2 of an electric motor 2 carried by longitudinal ralls 3 capable of moving in vertical guides 4 carried by the framework the said rails and their attachments being reciprocated by levers 5 operated from any suitable moving part of the apparatus, these levers preferably having, as shown, forked hook-shaped ends 5 which engage beneath V-shaped, or knife-edge, projections at suitable intervals along the rails these projections preferably being each in the form of a T head 6 upon a bolt 6 passing through a hole in the rail 3 and carrying below a similar V-shaped, or knife-edge, T piece, secured to the bolt-6, by a nut 6 and engaging with a correspondingly formed recessed bearing 3 beneath the rail.

Each of the aforesaid levers 5, which operate the spinning boxes as aforesaid, is preferably as illustrated a double-armed lever, one arm operating the longitudinal rail 3 and boxes 1 at one side and the other arm operating the longitudinal rail and boxes at the other side. They may be operated in any suitable way, for example from the electric motor of the apparatus, or from any other available source of power, conveying motion, for instance, to a shaft 7, carrying a cam-grooved roller 7 with which engages a pin 8 at the outer end of a lever 8, secured to the shaft 9. to which the double-armed levers 5, are alfixed.

The spinning boxes may be situated in an inclosed casing such as is shown at i 10. Through restricted openings, or guides, in the covers 11, carried by the said casin the motor spindles 2 and the stems 1 0 the spinning boxes pass. The tubular guides 12 for the threads being twisted may be supported in cover-pieces 13 which close openings in the casing over the respective spinning boxes, which cover-pieces 13, while excluding air as far as possible, allow of easy access when required. 1

The absence of overhead gear for reciproeating the tubular guides has the advantage that it enables the space at the upper part of each side of the machine to be utilized in order to give longer bearings 14: for the shafts lat of the rotatable rollers, or godets 14, which are used for guiding the threads downward to the saidtubular guides. These bearings 14 can be supported by double be extended as shown, to some distance from the outward support 15 of the aforesaid bearing 14:, by a continuation 14 which is stationary and this will not causethe thread, if it should escape the rotatable guide, or godet, to be coiled upon the shaft, while the inner ends of each shaft can be extended inward and be provided each with a bevel wheel 16 so that each pair of bevel wheels on two opposite shafts at either side of the apparatus can be driven by one bevel wheel 17 on a longitudinal shaft 17 which carries such bevel wheels to similarly drive the whole of the shafts of these rotating guides, or godets.

When lower rotating guides, or godets, are used for the threads immediately they leave the precipitating tanks, as illustrated at 18, these rotating guides, or .godets, may also be similarly provided with long shafts 18 and bearings 18 having stationary continuations 18 -next the rotating guide, or

odet, the said bearings and shafts extending toward the center of the apparatus where the shafts are furnished with the means by which they are rotated, which may consist, for example, as illustrated of wormwhecls 19 driven by worms 20 on shafts 20 extending longitudinally on either side of the center line of the machine so that all the lower revolving guides, or godets, on the respective sides of the machine are driven by one worm-shaft.

Owing also to the absence of gear for reciprocating the tubular guides, arrangements can be made for giving ready access to the interior of the apparatus by removing the parts which close openings 21 in the sides of the casing by which fumes passoff from the apparatus.

What I claim is:

1. In apparatus for use in the manufacture of artificial silk, a spinning box and means for reciprocating the same up and down during the spinning operation.

2. In apparatus for use in the manufacture of'artificial silk, a rotary spinning box and means for reciprocating the same up and down during the spinning operation.
